Haha... ironically, I'd peg Sayaka to be more fitting in taking Ryuko Matoi's role (which I'm guessing what Kyouko is supposed to be in this picture), since she's more similar to the hot-blooded 'justice-yearning' type character than Kyouko.

I agree, but the image might be partly a seiyu/voice actress joke. Sayaka's English dub voice actress Sarah Williams has been cast as Nonon in the English dub version of Kill La Kill.
